No, not the same thing... the ceramic heat emitters do not emit light. They do not get so hot that they glow red.

I love ceramic heat emitters, although they tend to dry out the cage. I set mine right on top in a regular ceramic light fixture. I think they are very much worth the money. I use 60w ceramic emitters in cages that are 12" high or less, 100w emitters for the tall cages. Never bought a 150w emitter.
